Malvertising Campaign Abuses Google’s DoubleClick to Deliver Cryptocurrency Miners - TrendLabs Security Intelligence Blog

On January 24, 2018, we observed that the number of Coinhive web miner detections tripled due to a malvertising campaign. We discovered that advertisements found on high-traffic sites not only used Coinhive (detected by Trend Micro as JS_COINHIVE.GN), but also a separate web miner that connects to a private pool. Attackers abused Google’s DoubleClick, which develops and provides internet ad serving services, for traffic distribution. Data from the Trend Micro™ Smart Protection Network™ shows affected countries include Japan, France, Taiwan, Italy, and Spain. We have already disclosed our findings to Google. We detected an almost 285% increase in the number of Coinhive miners on January 24. We started seeing an increase in traffic to five malicious domains on January 18. After closely examining the network traffic, we discovered that the traffic came from DoubleClick advertisements.
